This release of Rel<\/em>, an implementation of Date & Darwen’s Tutorial D<\/strong> database language, improves the user interface and fixes some bugs.<\/p>\n

The following enhancements have been made:<\/p>\n

– Rel<\/em> UI: Opening a relvar in Edit mode now positions the cursor in the blank row at the bottom, ready to enter a new tuple. Cursor keys may be used to navigate, and Ctrl\/Cmd-Cursor keys may be used to jump to top\/bottom or right\/left.<\/p>\n

– Rel<\/em> UI: Font scaling has been improved when using alternative output display on HiDPI Windows displays.<\/p>\n

– Rel<\/em> UI: The bundled Java runtime is now version 8u161.<\/p>\n

– Rel<\/em> DBMS: Using SAME_HEADING_AS(…) in a relation literal heading was previously not permitted. E.g., REL SAME_HEADING_AS(S) {} was a syntax error. It is now permitted.<\/p>\n

– Rel<\/em> DBMS and Rel<\/em> Client now check for and correctly handle ‘null’ source code.<\/p>\n

The following bugs have been fixed:<\/p>\n

– Rel<\/em> UI: Cut\/copy\/paste\/selectAll drop-down menus and keyboard shortcuts now work consistently and are generally available wherever they should appear.<\/p>\n

– Rel<\/em> DBMS: ABS(n) always returned a RATIONAL value, even if n was INTEGER. Fixed.<\/p>\n

– Rel<\/em> UI: <\/p>\n

Given: Ubuntu 16.xx, 17.xx and other GTK3 environments.<\/p>\n

Result: Multiple GUI failures similar to those when using the
\nEclipse IDE under GTK3.<\/p>\n

Fixed. Startup forces GTK2. Some issues remain, but at least it’s
\nusable.<\/p>\n

– Rel<\/em> UI: <\/p>\n

Given: In the relvar Edit mode, press “Go to INSERT row” button on
\nrelvar with high enough cardinality to require scrolling.<\/p>\n

Result: It was was supposed to do what Ctrl-End should also do:
\nposition the display on the blank row and put the cursor in it. It
\ndoesn’t.<\/p>\n

Fixed. Ctrl-Cursor preferred over Ctrl-End.<\/p>\n

– Rev:<\/p>\n

Given: Create an Expression and set its text to “WRITELN ‘&blah'”.<\/p>\n

Result: The & won’t show. If you change the text to “WRITELN
\n‘&&blah'”, it shows &, but is treated as “WRITELN ‘&&blah'”. <\/p>\n

Fixed.<\/p>\n

– Rel<\/em> DBMS:<\/p>\n

Given: viewtopic.php?f=2&t=1527&p=2863#p2863<\/p>\n

Result: Fatal error instead of semantic error.<\/p>\n

Fix: Now throws semantic error, plus gives a helpful hint for fixing
\na typical error.<\/p>\n

– Rel<\/em> DBMS:<\/p>\n

Given: S GROUP {blah} AS rva<\/p>\n

Result: Java NullPointerException due to undefined attribute ‘blah’.<\/p>\n

Fixed.<\/p>\n
